In recent years, the construction of large-scale satellite constellations, so-called mega-constellations, consisting of hundreds to thousands of satellites has begun, increasing the risk of satellite collisions in orbit. In addition, space debris such as uncontrollable satellites due to malfunctions and debris from rockets is increasing.
With such a rapid increase in space objects such as satellites and space debris in outer space, there is an increasing need for creating international rules for avoiding collisions of space objects in space traffic control (STM).

Patent Document 1 discloses a technique for forming a satellite constellation composed of a plurality of satellites in the same circular orbit.

Conventionally, there is a mechanism in which the Combined Space Operations Center (CSpOC) in the United States continuously monitors space objects and issues an alarm when approach or collision between space objects is foreseen. Manned space stations and commercial communication satellites carry out evasive operations when deemed necessary in response to this warning.

JP 2017-114159 A

With the increase in space debris, the increase in the number of satellites due to the emergence of mega-constellations, and the improvement in ground surveillance capability, it is becoming difficult to continue the conventional warning issuing service by the US CSpOC.

Embodiment 1.
An example of a satellite constellation that is a premise of the space information recorder according to the following embodiments will be described.

FIG. 1 is a diagram showing an example in which a plurality of satellites work together to realize a communication service over the entire globe of the earth 70 with respect to the ground.
FIG. 1 shows a satellite constellation 20 that provides global communication services.
Each satellite of a plurality of satellites flying in the same orbital plane at the same altitude overlaps the communication service range to the ground with the communication service range of the following satellite. Therefore, according to such a plurality of satellites, a communication service can be provided to a specific point on the ground while a plurality of satellites on the same orbital plane alternate in a time division manner. In addition, by providing adjacent orbital planes, it becomes possible to cover the area of communication services to the ground between adjacent orbits. Similarly, a number of orbital planes approximately evenly spaced around the earth would allow communication services to the ground over the globe.

FIG. 2 is a diagram illustrating an example of multiple satellites in a single orbital plane providing an earth observation service.
FIG. 2 shows a satellite constellation 20 for implementing earth observation services. In the satellite constellation 20 of FIG. 2, satellites equipped with earth observation devices, which are radio sensors such as optical sensors or synthetic aperture radars, fly in the same orbital plane at the same altitude. In this way, in the satellite constellation 300, in which the imaging range of the ground is delayed by time and the following satellites overlap, a plurality of satellites on orbit alternately alternately time-divisionally to capture a ground image with respect to a specific point on the ground. provide earth observation services.

Thus, the satellite constellation 20 consists of a constellation 300 of satellites in each orbital plane. In the satellite constellation 20, satellite constellations 300 cooperate to provide services. The satellite constellation 20 specifically refers to a satellite constellation consisting of one group of satellites by a telecommunications service company as shown in FIG. 1 or an observation service company as shown in FIG.

FIG. 3 is an example of a satellite constellation 20 having multiple orbital planes 21 that intersect near the poles. Also, FIG. 4 is an example of a satellite constellation 20 having multiple orbital planes 21 that intersect outside the polar regions.
In the satellite constellation 20 of FIG. 3, the orbital inclination angle of each orbital plane 21 of the plurality of orbital planes is about 90 degrees, and the orbital planes 21 of the plurality of orbital planes exist on different planes.
In the satellite constellation 20 of FIG. 4, the orbital inclination angles of the orbital planes 21 of the plurality of orbital planes are not approximately 90 degrees, and the orbital planes 21 of the plurality of orbital planes are on different planes.

In the satellite constellation 20 of FIG. 3, any two orbital planes intersect at points near the poles. Also, in the satellite constellation 20 of FIG. 4, any two orbital planes intersect at points other than the polar regions. In FIG. 3, collisions of satellites 30 may occur near the poles. Also, as shown in FIG. 4, the intersections of a plurality of orbital planes with an orbital inclination angle of more than 90 degrees move away from the polar regions according to the orbital inclination angle. Moreover, there is a possibility that the orbital planes intersect at various positions including near the equator depending on the combination of the orbital planes. This diversifies the locations where satellites 30 may collide. The satellite 30 is also called an artificial satellite.

In particular, in recent years, the construction of large-scale satellite constellations of several hundred to several thousand has begun, increasing the risk of collision of satellites in orbit. Debris such as uncontrollable satellites and rocket wreckage is also increasing. A large satellite constellation is also called a mega constellation. Such debris is also called space debris.
Thus, with the increase in debris in outer space and the rapid increase in the number of satellites including mega-constellations, the need for space traffic control (STM) is increasing.

In addition, for the orbital transition of space objects, post-mission deorbit (PMD) in orbit or malfunctioning satellites, and ADR that deorbits debris such as floating rocket upper stages by external means such as debris removal satellites. The need is growing. An international discussion has started on the necessity of such ADR as STM. Here, PMD is an abbreviation for Post Mission Disposal. ADR is an abbreviation for Active Debris Removal. STM is an abbreviation for Space Traffic Management.

In addition, due to the strengthening of the system including international cooperation in Space Situational Awareness (SSA) and the improvement of observation accuracy, the size of space objects that can be grasped can be monitored even smaller. Also, the total number of space objects that can be monitored is increasing.

The rapid increase in the number of space objects accompanying the development of mega-constellations is one of the causes of increased collision risk in outer space. However, if collisions between man-made space objects could be avoided as a result of man-made activities such as STM, the risk of chain collisions triggered by collisions with debris floating in outer space would still be a serious problem.
Even if the debris itself is a microscopic object, there is a risk that the satellite will be destroyed explosively under collision conditions with a high relative velocity, and there is a risk of a chain reaction of high-order damage due to scattered fragments.
A mega-constellation of thousands of satellites has been announced with plans to fly about 2,500 satellites at the same altitude. During normal operation, the mainstream policy is to avoid collisions within the system by managing the flight position of the previous satellite over time. However, if a debris collision triggers an abnormality in orbital attitude control of one satellite and deviates from the initial time management control, or if debris scatters, other satellites flying at the same orbital altitude very high risk of colliding with

In order to avoid such a collision risk, it is rational to centrally manage debris orbital information and mega-constellation orbital information and perform collision prediction analysis. It has been said that about 20,000 pieces of debris the size of a basketball can be monitored in the area of SSA. Furthermore, it is said that 200,000 large softball balls will be able to be monitored in the future due to the improvement of the monitoring capability called the space fence in the United States.
If SSA operators maintain and manage 200,000 pieces of debris information while updating the information, there are many problems in centrally managing the orbital information of more than 10,000 aircraft held by mega-constellation operators. There is For example, in the case of using not only orbit prediction based on natural phenomena but also orbit attitude control possessed by the satellite itself, it is necessary to reflect the effect in orbit prediction analysis, which entails a huge amount of work. Also, the mega-constellation operator does not always disclose the latest and highly accurate satellite information to the SSA operator. Also, monitoring 200,000 pieces of debris is by no means a necessary and sufficient scale. Even microscopic debris smaller than a softball could have the potential to destroy a satellite. Hence, there will be an increasing need to monitor even smaller size and huge amounts of debris in the future.
On the other hand, it is not realistic for a mega-constellation operator to centrally manage 200,000 pieces of debris information, including the amount of work involved. Furthermore, it is not easy to centrally aggregate the information of multiple mega-constellation operators.

Under the circumstances as described above, it is preferable for the SSA operator to pass the debris orbit information to the mega-constellation operator and for the mega-constellation operator to analyze collisions with satellites in its own system. Mega constellations have thousands of satellites at specific orbital altitudes. Therefore, as debris orbital information, if there is predicted time, position, and velocity vector information that the mega-constellation will pass through a specific orbital altitude, the mega-constellation operator can identify satellites with a collision risk and predict collisions. Analysis can be performed.

***Description of the effects of the present embodiment***
Normally, when a space object collision was foreseen, the SSA operator issued an approach warning or collision warning, and the space station ISS or satellite operator took evasive action as necessary. With the advent of mega-constellations, it will be difficult for external organizations other than mega-constellation operators who possess high-precision orbital information to perform collision prediction analysis. Therefore, it is necessary to review such warning systems.
In this embodiment, attention is paid to a specific orbital altitude at which a mega-constellation operator deploys satellites comprehensively in the sky. Then, a system for deorbiting and issuing an intrusion warning to the altitude when a satellite in orbital descent or debris is predicted to pass through the altitude has been described.

In addition, in the vicinity of LST 10:30, in dense orbits at altitudes of 500 to 800 km, or in dense regions such as polar and high latitude regions, there are many satellites with a high collision risk. In addition, there is a high possibility that there will be a large number of relevant business operators, and there is also a concern that evasive action cannot be implemented. The vicinity of LST 10:30 is a sun-synchronous orbit frequently used by optical satellites for earth observation purposes. The polar and high latitude regions are frequently passed by polar orbiting satellites.
Therefore, in the present embodiment, even if it is predicted that a satellite in orbital descent after deorbiting or debris will invade a dense orbit and a polar/high latitude region, an intrusion warning for the dense orbit is issued. He explained the system for issuing orders.

For mega-constellation intrusion warnings, mega-constellation operators can use their own high-precision trajectory information to perform collision analysis and, if necessary, take action to avoid collisions.
Concerning intrusion warnings in dense orbits and polar/high latitude regions, there is a possibility that collisions can be avoided by notifying the concerned parties and debris removal contractors and removing debris from the intruding objects.

As space insurance for collision accidents, existing space insurance has covered accidental accidents or accidental failures. On the other hand, the orbital altitude adopted by the mega-constellation, or the situation in which an intrusion warning is issued when passing through dense orbits and polar/high latitudes, can be regarded as a foreseeable collision rather than an accidental accident. .
Furthermore, in the event of a collision accident, there is a high risk of chain collisions with satellites flying in the vicinity, resulting in increased damage.
Therefore, in order to apply existing insurance, the accident frequency and the assumed scale of damage are significantly different. For this reason, it is necessary to review premium rates, deductibles, terms and conditions, and insurance premiums.
Especially for mega-constellations, it is rational to purchase insurance for a group of satellites, unlike the method of purchasing space insurance for each individual satellite.
Ad-hoc space object collision insurance can be newly established to distinguish accidental accidents from foreseeable collisions, which can be purchased after approach warning or collision warning is issued, and can be terminated after the foreseen risk is resolved. A mechanism can be considered. Although the space object intrusion warning system is a new concept for this, it would be reasonable to have a mechanism that allows a person to purchase space collision insurance after an intrusion warning is issued, similar to approach warnings or collision warnings.

In response to the intrusion warning, the intruder, the mega-constellation, the dense orbit, and the polar transit satellite may take evasive action. In addition to this possibility, there is also a means for debris removal operators to remove intruding objects to avoid collisions. For this reason, there are many options for coping actions.
Furthermore, it is necessary to assess the risk of taking evasive action itself, such as the risk of colliding with another space object as a result of taking evasive action. If it is judged that taking evasive action increases the risk, there is also an option of "do not take evasive action against intrusion alarm".
Difficult negotiations between the parties will be necessary, such as which of the parties will take evasive action, whether to outsource to debris removal contractors, and how to share the cost burden. Therefore, consulting or advice from experts in collision avoidance support is also effective.

The space information recorder according to the present embodiment can accurately predict the invasion of space objects into dense areas such as mega-constellations, dense orbits, and polar/high latitude areas. In addition, it is possible to accumulate detailed information on the space object at the time of collision.

In the vicinity of LST 10:30 of the sun-synchronous orbit, which is frequently used by earth observation optical satellites, at an orbital altitude of about 500 km to 800 km, satellites of many countries and many companies are currently flying. In the future, it is expected that the satellites of many stakeholders will operate in dense orbits in a daisy chain. If the debris intrudes in substantially the same plane as this dense orbital plane, many satellites will be subject to proximity or collision warnings.
Furthermore, in this orbit, satellites such as small satellites called CubeSats, which do not have means to take avoidance action by themselves, cannot take avoidance action even if a collision warning is issued. If some satellites take evasive action and others do not in a dense orbit, there is a secondary collision risk of colliding with another satellite despite the intention to avoid it. Not necessarily.
Also, if there is an error in the estimated time of debris arrival, and if the flight direction of the satellite is close to the flight direction of the debris, the distance will be large in terms of distance, and many satellites will be exposed to the risk of collision.
Since a low earth orbit satellite completes one orbit in about 90 to 100 minutes, if there is an uncertainty of about ±50 minutes in the arrival of debris, all satellites in the orbital plane are at risk of collision.
Another problem is that when a collision accident occurs on a dense orbit, the chain of collisions is very high.
Therefore, when the trajectory prediction of debris entering a dense orbit is found, it is rational to immediately issue a warning to debris removal operators and remove the debris.

The debris removal satellite 30a includes a trapping device 36 for trapping debris in addition to the configuration of the satellite 30 described with reference to FIGS. The debris removal satellite 30a captures debris in response to a control command 56 from the debris removal business device 45, and in the deorbit process until re-entry into the atmosphere, the debris removal satellite 30a descends while avoiding areas where there is a high risk of collision with space objects. Perform active control operation. Active control operation during orbital descent is also called active deorbit operation.
The debris removal business device 45 may be mounted on the ground facility 702 . Moreover, the debris removal business device 45 may be mounted on the debris removal business device 45 or may be mounted on another device that communicates with the debris removal business device 45 .

Debris removal satellites 30 a capture debris and perform active deorbit operations based on control commands 56 .

The satellite orbit region 301 may also include high latitude regions including polar regions. The alarm notification unit 130 notifies an intrusion alarm 111 for warning debris intruding into a high latitude region including the polar region to a debris removal business device 45 used by a debris removal business that removes debris.

FIG. 25 is a diagram showing an orbital example of debris entering the satellite orbital area 301 according to the present embodiment.
In the constellation of polar orbiting satellites, all orbital planes pass through the polar regions, so the polar regions are dense regions.
If there is an error of ±50 minutes in predicting the arrival time of debris, there is a possibility that collision risks will occur for all satellites in all orbital planes. Also, even if you want to take evasive action, the evasive action that can be contributed by the propulsion device equipped with the normal satellite is only about changing the orbital altitude, and it may not be an effective means of risk aversion. Difficult situations can arise.
Therefore, when the trajectory prediction of debris invading high latitude regions including polar regions is found, it is rational to immediately issue a warning to debris removal contractors and remove the debris.

In this embodiment, an open architecture data repository that publishes orbital information of space objects will be described. In the following, the open architecture data repository may be referred to as OADR800. OADR is an abbreviation for Open Architecture Data Repository.
A specific example of the OADR 800 will be described below.

<Specific example 1 of OADR800>
The OADR 800 comprises the space information recorder 100 described above.
OADR 800 comprises space information recorder 100 as a public database. Equipping the OADR 800 with the space information recorder 100 has the effect of enabling information sharing among operators and contributing to risk avoidance.

<Specific example 2 of OADR800>
The OADR 800 may comprise the collision avoidance assistance system 200 described above.
Concrete example 2 is a form in which the collision avoidance support system 200 is provided as an implementation form of the OADR 800 to actively contribute to collision avoidance. Note that the OADR 800 may be equipped with a business device such as an SSA business device or a debris removal business device that contributes to space situational awareness.

When the OADR 800 is maintained as a public institution, it is possible to perform risk analysis and evaluation analysis including confidential information, process the orbital information into a state that can be disclosed, and make conditional information disclosure possible. Therefore, it becomes possible to effectively contribute to ensuring flight safety in space.

<Specific example 3 of OADR800>

The OADR 800 shares information with all or part of the SSA business device 47, the mega-constellation business device 41, and the debris removal business device 45, and requests the implementation of the information management method described above.

<Specific example 5 of OADR800>
FIG. 26 is a diagram showing an example of OADR 800 according to this embodiment.
The OADR 800 comprises a database 801 storing orbital information of space objects, and a space information management server (hereinafter referred to as server 802).
The database 801 includes a first database 81 that stores non-public information and a second database 82 that stores public information.
The server 802 performs risk analysis by referring to the first database 81 and the second database 82, and identifies and manages the free public information and paid public information in the second database 82. FIG. Specifically, the server 802 includes a control unit 83 as a functional element, and the functions of the server 802 are implemented by the control unit 83 .

Space objects include space objects whose orbital information is kept private due to security needs. On the other hand, when performing risk analysis such as approach or collision, it is necessary to perform risk analysis including non-public information. Therefore, it is rational to separate the databases to avoid the risk of information leakage.
Moreover, there is a possibility that public information includes both free public information and fee-based public information, and it is necessary to identify and manage the information when disclosing information by OADR.
The OADR centrally separates non-public data from public data and then manages public information by distinguishing whether it is paid or not, thereby enabling appropriate information management in accordance with the Need to Know principle.

<Specific example 6 of OADR800>
In specific example 6, the server 802 performs risk analysis with reference to the first database 81 and the second database 82, and identifies and manages unconditional public information and conditional public information in the second database 82. FIG.

The space insurance business equipment 48 is a business equipment used by the space insurance business mentioned above.
The OADR 800 may apply Example 8 to other business devices as needed.

<Specific example 9 of OADR800>
FIG. 27 is a diagram showing another example of OADR 800 according to this embodiment.
OADR 800 comprises space information recorder 100 described above and server 802 .
The space information recorder 100 comprises a first database 81 storing public information and a second database 82 storing non-public information.
The server 802 stores space object information including non-public information in the space traffic management device 49 provided in the CSpOC, the SSA business device 47, the collision avoidance support business device, the mega constellation business device 41, and the debris removal business. The information is acquired from all or part of the equipment 45 and stored in the second database 82 . The server 802 also generates conditional public information that limits the disclosure target and public content, and stores it in the first database 81 . The server 802 is limited to specific business devices among the SSA business device 47, the collision avoidance support business device, the mega constellation business device 41, the debris removal business device 45, and the space insurance business device 48. to transmit the conditional public information.
The OADR 800 may apply Example 9 to other business devices as needed.

A space traffic management device is a device that continues to monitor space objects and implements space traffic management. For example, there is a space traffic management system as a mechanism for CSpOC in the United States to continuously monitor space objects and issue an alarm when space objects approach or collide with each other is foreseen.

Confidential information on space objects held by CSpOC, which contributes to security, may be released only to OADR, but it is necessary to analyze and foresee the risk of approach and collision, including confidential information.
After processing the information into information that can be disclosed conditionally, even private business operators can take action to avoid collisions by sharing conditionally public information that contributes to collision avoidance support, limited to business equipment related to collision risk. .
In addition, among the space object information held by private business operators, collision avoidance becomes possible by similarly processing the space object information that cannot be disclosed to the general public by the OADR into conditionally openable information.

The functions and effects of the OADR 800 according to this embodiment will be further described below.

Investigations are underway to establish a public information system called OADR for the orbital information of space objects, share the information among operators, and ensure the flight safety of space objects.
When OADR is developed as a public organization for international collaboration, it is possible that the authority to give instructions or requests to business operators across national borders will be granted.
For example, in order to centrally manage the orbital information of space objects held by operators around the world, it would be rational if they could instruct or request the provision of orbital information to OADR under rules based on international agreements.

If a specific country establishes an OADR as a public institution, it may be given the authority to give instructions or requests to the operators of that country.
On the other hand, there is also the possibility of a system in which information is unconditionally disclosed to business operators in the country concerned, and information is disclosed conditionally to business operators in other countries.
As disclosure conditions, it is possible to set charges, price setting, restriction on disclosure items, restriction on accuracy of disclosed information, restriction on frequency of disclosure, non-disclosure to specific business operators, and the like.
For example, there may be differences between the country concerned and other countries, whether it is free or for a fee, or the price for obtaining information. You will be influential in your point of view.

Confidential information on space objects that contributes to national security should be kept private by the OADR, which is maintained by the government as a public institution, but not disclosed to the outside world. For this reason, the OADR may have a database for storing non-public information in addition to the database intended for information disclosure.
Also, among the space object information held by private business operators, it is not appropriate to disclose information that cannot be disclosed to the public due to trade secrets, etc. There is also information that does not exist.

When conducting risk analysis and analysis evaluation related to approach and collision of space objects, it is necessary to target the orbital information of all space objects regardless of whether they are confidential or not.
For this reason, it is rational for OADR as a public institution to conduct risk analysis including confidential information and to disclose the results of the analysis and evaluation with the following conditions. For example, when OADR foresees a danger, it processes information that can be disclosed, and then releases only the orbital information for the dangerous time zone to the disclosure target that contributes to avoidance of danger. Put restrictions on the content and make it conditional disclosure.

If the number of objects on orbit increases in the future and the risk of approaching or colliding increases, the debris removal operator will remove dangerous debris, and the mega-constellation operator will change the orbital position or passage timing to avoid collisions. A variety of risk avoidance measures such as means are required. If the OADR, which is a public organization, can instruct or request business operators to take action to avoid danger, it can be expected to have a great effect in ensuring the safety of space flight.
Emerging countries with little experience in space business and lack of information to help avoid danger, space objects managed by venture businesses, universities, etc. are foreseen to enter the orbital altitude zone where the mega constellation flies. , and OADR mediate and transmit information to necessary business operators, so that danger can be avoided quickly and effectively.

In addition, we can contribute to the promotion and industrialization of space traffic management by implementing risk avoidance measures and arranging or introducing space insurance to private businesses.
OADR can be implemented in a form that only has a public database, or in a form that has danger analysis means, collision avoidance support means, or SSA means and actively contributes to danger avoidance. In addition, there are various possibilities, such as a mode of contributing to risk avoidance through information management by executing instructions, requests, mediation, or introductions to business operators.

When the SSA operator conducts debris collision prediction analysis and finds the risk of approaching or colliding with the satellites that make up the mega-constellation, it is rational to determine avoidance actions as follows. Unlike conventional satellites that issue approach/collision warnings for individual satellites, intrusion warnings are issued to mega-constellation operators as passage forecasts for the orbital altitudes that make up the mega-constellation, and the mega-constellation operators detect the corresponding satellites. identify and determine avoidance behavior.
Similarly, it would be reasonable to issue an intrusion warning for dense areas such as dense orbital planes and polar regions, and create a mechanism that includes entrusting coping actions to debris removal operators. be. In the above-described embodiments, the space information recorder and the OADR have been described in which the space information recorder has a means for the SSA operator to issue an alarm when debris enters a specific altitude or a dense area.
